Burleson’s environmental staff has extensive experience performing environmental characterization and remediation projects. Projects have been conducted under the Resource Conservation and Recovery Act (RCRA) and the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). We use a strategic approach that incorporates site specific issues at each remediation site.

Before implementing remediation, Burleson first ensures that site characterization is sufficient to support the necessary decisions. Burleson’s strategy is to develop two key elements to ensure that data collected during a field investigation will ultimately lead to appropriate site characterization and aid in selecting a remediation technology. The first element is to develop a conceptual site model (CSM) in which chemical releases, exposure pathways, and receptors are identified, and the second element is to develop data quality objectives (DQO). Burleson staff use the DQO process recommended by the EPA to ensure that sufficient data are collected. By developing a CSM and DQOs before a field investigation, sufficient samples are collected and appropriate parameters are analyzed.

Burleson staff used CSM and DQO tools at a naval installation site. The CSM indicated that groundwater was considered to be a threat only to aquatic receptors and not to human health. We then applied this information to establish appropriate detection limits for analysis of groundwater samples. DQOs were used to ensure that sufficient samples were collected and that collected samples were analyzed for parameters that would influence potential treatment technologies. By using these tools, our clients received the best value from the investigation.

Burleson staff has used a probabilistic risk assessment approach for allowing higher concentrations of polychlorinated biphenyls (PCBs) to remain in soil than would normally be allowed.

In Burleson’s experience, it is crucial to involve engineers, geologists, and regulatory specialists during all stages of an environmental investigation and remediation project. Our comprehensive approach and extensive experience remediating environmental contamination make us an ideal firm to solve your environmental problems.
